This object I accomplish by the`use ot' an instrument constructed substantiallyas hereinafter descril-)ed-tha-t is t0 say, the instrument consists of a reservoir, A, in which the material or slibsl'ance-the Vapor, gas',- or atmosphere ot' which i.' to be inhaled-'is placed.` In thetop of this reservoir a. tube7 I3, is screwed in the manner substantially as shown. rlhe upper end ot' thisI tube is fitted with a cap, cymade somewhat inl the/form ot a dome and fitted with nipples F, to which flexible tubes l) are attached, theends whereotA are litted with suitable tips E t-o g'o into the mouth or nose of the patient, and may, of course, be made ot' an)r t'orm best adapted t'or that purpose.

When itis desirous to introduce atmospheric air, either hot or cold, in limited quantities, the reservoir ibis taken oii" and the chamber shown in Fie'. 3 is put in its place. And when it is desirous to use an ethereal inhalation, the sponge I-I the purpose ot the invention without material inodilcation. l claim`as my inventionlbe described inhaling instrumpnt, consisting ot' the reservoir-A fitted with the Valve and perlbratious as described, the tube B made and applied to the reservo' as set forth, and a flexible tube or tube, l), ltted with suitable tips and applied to the tube P over a perthrated cap, all
